Thanks! I used 8K EXRs out of Gaea for the displacement and color. Loaded the displacement through a heightfield load node, then a resize node and an altitude adjust node. I think there's a few things that made a difference in this scene from what I've tried before:
- I concentrated the entire 8K displacement map into a 100x100 square in Terragen. That helped give a lot more detail in the foreground and midground but also restricts the POV.
- I spent more time on the Gaea colormap, adding more complexity, which I think increases the sense of detail on the surface.
- I intentionally tried to use the added plants and fake stone gravel to convey the scale I wanted, making the nominally 5 km Gaea terrain seem much smaller when resized in Terragen.
Like I said before, this is one of the first close-ups I've been really happy with out of Gaea, so we'll see if it's reproducible, or if I just got lucky this time.
What I found impressive is that it only took two nodes in Gaea to make that geometry, a Perlin node, and the Stacks node in 'desiccated mode. Here are some WIP pictures.
I haven't seen anyone hosting or selling Gaea terrains, but I haven't really looked either. The output files are relatively large, this one was a gigabyte between the terrain and color images.
